I've got a route that I want to be able to pass nullable values to. I was using MVC 1 but updated my solution to MVC 2 to take advantage of UrlParameter.Optional.
My route look like:
[Code]....
Which works fine if I go to http://localhost:1234/Search.aspx/l-1/t-1/p-1/s-1 but when I go tohttp://localhost:1234/Search.aspx/l-/t-/p-1/s- or any combination with missing parameters I keep getting 404's.
Also on a related note since I've upgraded to MVC 2 I can no longer use RedirectToRoute for the above route I get the following error: No route in the route table matches the supplied values. Whereas in MVC 1 it would redirect to it without any problems.
Was looking at asp.net mvc complex routing for tree path as an example of how to define a custom route handler for my MVC app. Essentially, I want to give the end user ultimate flexibility in defining the URL for any given page, so I provide them with a field in the interface to specify their own custom URL.
My custom route handler is basically a wild-card handler. It will do a lookup and if it finds a match, map it accordingly. However, if no match is found, I want it to fall back and find the next rule that matches in the global.asax. Is that possible? Or do I essentially need to code the mappings that used to exist in my global.asax into my custom route handler?
here is my code for selectiong some records from db table
string strSql = "select * from mtblNBD where SentTo=@SentTo and InternalStatus Is NULL order by DeadLine desc"; SqlCommand com = new SqlCommand(strSql, con); com.Parameters.Add("@SentTo", SqlDbType.NVarChar, 50).Value = (string)Session["uname"];
here I am using parameters for SenTo field but not for NULL so it is ok... or should I use parameters for this field where value is NULL , if yes then how can I use parameter for this
I want to create a method with optional parameters in my wcf service. I am doing it like this

When I try to use it in my client application and try to pass the values only for first two parameters it gives me an error that"Argument not sepecified for parameter Status"
I have a controller method that is called with many different combinations of URL's. To overcome issue i am using optional parameters.here is my controller method signature...public ActionResult localMembersSearch(string Gender, string calling, [Optional]string Region, [Optional]string County, [Optional]string Town, [Optional]string queryvalues)the first two parameters are not optional but always expect
I want to add optional parameters in my routing table.For example I would like the users to browse a product catalog like this:http://www.domain.com/browse/by-category/electronics/1,2,3 etc
I've already implemented URL routing in my app but there are cases where I may or may not get a paramter. In particular, I'm trying to come up with a good way to handle multi-language support. For example, if my regular URL is /SomeCategory/Friendly-Topic-URL, I want to have an optional language selector at the end but I'd like to be optional. So, if I get /SomeCategory/Friendly-Topic-URL/es, that should bring up the topic in Spanish but if get nothing, that should bring up English.
I'm trying to implement a search function on an incident logging page that is working fine. Currently I am only able to search against one criteria at a time, using the following route:
I'm using the iis7 URL Rewrite module and it's working fine, except for two things. Being new to this, I might be missing something obvious.
1) My URL gets converted from www.mysite.com/search.aspx?fName=John&sName=Smith to www.mysite.com/John/Smith. This works fine, but if I add a trailing / , a few images on the site disappear, wheras a few don't. (They're all in the same location). However, the search results are fine.
2) Is it possible to make cerain querystrings optional? Server side, this is implemented (i.e. if nothing is entered, then assume a default value). But how would this work with the URL rewrite module? e.g. www.mysite.com/John would search for John and use a default value for the sName parameter.
Basically, my question is: how do I specify optional parameters to a WebMethod when providing JSON data?
I know I can reduce the parameters down to just the required values, and then use HttpContext.Request.Params to read the values of optional paramaters, but I would have thought the way I have tried here should have worked.
EDIT
The XMLHttpRequest.responseText value for the error is:
Invalid JSON primitive: staffcode.
This is throwing me even more off the scent of the problem :(
I have a GridView bound to an DataSource query with parameters tied to form controls.What is the standard / best-practices way to handle optional query parameters?
I'm creating a webpage with serveral web controls to set search parameters for querying an SQL table. My plan is to use a TableAdapter to hold the query. If the user decides not to use one, several, or any of the web controls to filter their search, I want the SELECT to execute without complaining that it doesn't have parameter values. Should my SQL query look like
I have got a problem about setting the optional parameter to NULL in sql sp. Initially I set all the parameters null in the sql sp. That's OK. But I would like to set the parameters to Null again if a particular parameter has a value of - 1 by using the "IF ELSE" statement block. However, the problem was that I was unable to set the parameter to NULL in the IF ELSE statement. So please correct my IF ELSE statement in the store procedure. This is really urgent and important for my project.
spGetMealsByNutritions] @MealTypeID Int, @Gluten Bit = Null, @Dairy Bit = Null, @Egg Bit = Null, @Fish Bit = Null, @Veg Bit = Null, @Pork Bit = Null, @Beef Bit = Null, @Soy Bit = Null, @Sesame Bit = Null [code]...
I have a data grid with a lot of information on it - to easily filter the data, I would like to be able to pass parameters to it. My problem is that I do not want the parameters to be required. So if I just put 1 or 2 of them in the query string, I would like for it to return all of the data related to those two parameters.I am using a data grid & stored procedures:My Stored Procedure looks like this:
I am using NLog for logging in an ASP.Net application and making use of the database target with Microsoft Sql Server.I have some logging parameters that are optional and not always specified. I would like these to be written as null when they are not provided, however NLog seems to always write them as empty strings.
Is there a way to configure it to write null as the default?
In Area VIPUsers I have controller ProfileController and other controllers.
If I want every method in ProfileController to have parameter (id) and every method in other controllers to have parameter (userid and id) how would I map it?
Would it be
context.MapRoute("ProfileMapping", "VIPUsers/Profile/{action}/{id}", new {controller="ManageUsers", id=""});
and then map a default one for all the controllers?
context.MapRoute("Default", "VIPUsers/{controller}/{action}/{userId}/{id}", new {action="Index", userId="", id = ""});
If I go to a page on ProfileController and give it two parameters after {action} (VIPUsers/Profile/SomeAction/4/4/), it'd use the second mapped route. Is that correct?
I have spent several hours today reading up on doing Custom Routing in ASP.NET MVC. I can understand how to do any type of custom route if it expands from or is similar/smaller than the Default Route. However, I am trying figure out how to do a route similar to:
/Language/{LanguageID}/Question/{QuestionID}/
And what I would like, too, is similar to how SO works. Something like:
